l Application filed March 9, 1914. Serial No. 823,524.

clear, and exact description thereof, refer? ence being had to theaccompanying drawings, in which like letters refer to like parts.

The object of this invention is to provide means for equipping vehiclewheels to prevent skidding, slipping or spinning'of the same, and tomake a very strong construction whichwill resist any pull which theengine may exert.

One feature of the invention consists in providing at intervals aroundthe tire of the wheel, metal anti-skidding means with means passinginside the rim of the wheel for securing itin place, the ends of themetal portion being yielding so that the device will always be held inplace under tension and will accommodate itself to variations in thetire; whether from wear or slight deflation.4 The ends of the metalanti-skidding means are made of a good quality ofspring steel and areturned outward so that they will yield and maintain the device alwaysunder tension.v With this arrangement there is no possibility of thedevice being thrown off of the wheel by the pull of the engine and theneed of set screws-or other complex and annoying apparatus for adjustingthe tension or taking up the Wear of the device is obviated. In otherwords, it automatically adjusts itself to the varying conditions of thetire and continues at all times under tension. I

An additional feature of the invention is that the device may be easilyand quickly Aunderstood from the accompanying drawings and the followingdescription .and claim.

I n the drawings, Figure 1 is a side elevation of a portion of a wheelequipped with a number of said anti-slridding devices. Fig. 2 is aperspective view of one of the anti-skidding devices detached. Fig. 3 isa transverse section through the tire, clencher rim, wheel rim and apart of the wheel, showing the anti-shielding device in use.

In detail there is shown herein a wheel h aving spokes 10, wooden rim11, clencher rim 12 and pneumatic tire 13. These are all of the usualtypel of construction.

There is a spring metal anti-skidding device 15 which partiallysurrounds the tire 1.3 and on the tread portions there are spurs 16. The inner ends 17 of said anti-skidding metal member 15 are bentoutwardly, as shown in Figs. 2 and 3, and links 1S are connectedtherewith to which a leather strap 19 passes, and said leather strap eX-tends through the wheel over the wooden rim and is buckled at 20. Inmounting said anti-skidding means, the leather strap is pulled astightly as possible so as to put the spring ends 17 under tension. Anynumber of these anti-skidding devices may be placed on the wheel, asthought best. lith this arrangement the construction and expense andannoyanceof set screw devices for tightening and holding theanti-skidding met-.1l strip on the tire are obviated. 'The chief reasonfor this lies in the-spring 17 which automatically maintains the treadunder tension and accommodates it to variations in the wear andiniatedcondition of the tire. With this arrangement, the anti-skidding metalstrip will always be held tightly in engagement with the tire. Thelaterally extending spring ends 17 hold the parts away from the lateraledges of the clencher rim, as seen in Fig. 2. rlhe result is that a verypractical and acceptable anti-skidding device is provided here whichovercomes thc objections to similar devices heretofore.

` The invention claimed is:

The combination with a vehicle wheel having a tire rim, of ananti-skidding spring metal strip with its inner ends extending CIIlaterally outward, and means connected Xed my signature in the presenceof the with said spring ends which passes through Witnesses hereinnamed.
